Profiting from poverty

We consider whether and under what conditions it is morally illicit to profit from poverty. We argue that when profit counterfactually depends on poverty, the agent making the profit is morally obliged to relinquish it. Finally, we argue that the people to whom the profit should be redirected are those on whom it counterfactually depends.     

Symptoms of a Misunderstanding in Contemporary Academic Philosophy

This paper challenges a conception of philosophy that is seldom clearly expressed, yet appears to be prevalent in contemporary academic philosophy. On the website of the American Philosophical Quarterly, some sentences appear that articulate well the essentials of that assumption. This article discusses those sentences and assumes that they may be symptomatic of a widespread blindness to a fundamental aspect of the nature of philosophical study. The first part of the article consists of an analysis and criticism of the sentences in question. The second part investigates some possible defences of the sentences and the conception of philosophy they express.     

'Talk to me baby, tell me what's the matter now': Semiotic and developmental perspectives on communication in psychoanalytic infant treatment

Infants suffer to a considerable degree from disturbances in nursing, sleep, mood, and attachment. Psychotherapeutic methods are increasingly used to help them. According to case reports, psychoanalytic work with infants and mothers has shown deep‐reaching and often surprisingly rapid results, both in symptom reduction and in improved relations between mother and child. The clinical urgency of the method makes it important to study its results and theoretical underpinnings. Among the theoretical issues often raised in discussions on this modifi ed form of psychoanalysis, those addressing the nature of communication between analyst, baby, and the mother are the most frequent. For example, how and what does an infant understand when the analyst interprets to her? What does the analyst understand of the infant's communication? These issues are addressed by investigating the infant's tools for understanding linguistic and emotional communication, and by providing a semiotic framework for describing the communication between the three participants in the analytic setting. The paper also investigates problems with the traditional ways of using the concept of symbolization within psychoanalytic theory. The theoretical investigation is illustrated by two brief vignettes from psychoanalytic work with an 8 month‐old girl and her mother. demand for the breast.

Argumentation in and Across Disciplines: Two Norwegian Cases

This paper aims at exploring the challenges arising when teachers at secondary school level decide to cooperate about students’ argumentative writing. Two teams of teachers and researchers have met regularly during the school year, discussing students’ texts from a variety of disciplines. Going into two writing tasks in detail, the authors discuss the importance of scaffolding (support) in the teaching of argument. The paper includes a discussion of some specific textual features that are often touched upon in the meetings.     

Dark-adaptation of the human rod system: A new hypothesis

Following a long, full bleach, rod dark-adaptation curves from two normal trichromats were obtained with test fields of various size, exposure time and retinal eccentricity. The results show that there is a substantial region of threshold recovery with an approximately constant, linear slope of about 0.27 log per minute of dark-adaptation, which is independent of the test variables. It is suggested that the increase in sensitivity during this constant, linear slope is completely determined by changes in the concentration of bleached rhodopsin. The relationship between change of relative threshold (T) and fraction of bleached rhodopsin ( B ) is given by T=B ^3,7. This exponential law is well described by the displacement of the equilibrium between the active and inactive states of an allosteric enzyme built as a tetrarner.     

Mechanisms of long-term dark adaptation

It has previously been suggested that long-term dark adaptation is controlled by bleaching signals that regulate the activity of an allosteric, positively cooperative protein (Stabell et al., 1986a, b). Recent biochemical evidence strongly supports this assumption, indicating that the primary regulator of the light-sensitive channels in the plasma membrane of the outer segments of the photoreceptors is a homo-oligomeric, allosteric, positively cooperative protein. In this report, we discuss the possibility that signals from bleached photopigments may control the dark-adaptation process through the allosteric protein of the plasma membrane. It is suggested that the concentrations of the bleached photopigment and of the allosteric effector are reciprocal quantities.     

The factor structure of the Maslach Burnout Inventory in two Swedish human service organizations

The Maslach Burnout Inventory, MBI, is a well established measure of burnout. Its validity outside the USA is, however, uncertain. The aim of the present study was therefore to apply the MBI on personnel in two Swedish human service organizations, comparing factor solutions and scoring norms to the original results. The population consisted of 5730 employees in the Social Insurance Organization (SIO) and the Individual and Family Care section (IFC) of the social welfare agencies. Principal components analysis, principal axes and alpha factor analyses were performed, all with varimax rotation. The suggested three factor solution showed to be remarkably stable irrespective of type of analysis. Score levels were somewhat lower on two subscales in the Swedish population. The conclusion is that the psychometric properties of the MBI seem to be very satisfactory and stable, at least in comparison between Sweden and USA. It is suggested that the dimensionality of MBI is rather invariant, but that the score levels covary with national, cultural, or professional contexts within the human services.     

Research as a family therapy intervention technique

The utilization of the research process as an intervention has recently been described in the family therapy literature. However, it is important to draw a distinction between research as intervention and research as a unique family therapy intervention technique. From a family systems perspective, research as an intervention technique may make therapy more palatable for some families. A case study is presented in which this technique created the context for change for a family involved in a chronic illness research project.The author would like to thank Dr. Wendy L. Watson for her participation as a member of the clinical team and Drs. Fabie Duhamel and Wendy L. Watson for their helpful critiques on earlier drafts of this paper.Supported by a grant from the Albert Foundation for Nursing Research.     

Scotopic contrast hues displaced toward blue

Abstract.— Pre-stimulation with a neutral white light, in a dark-adapted state, produced a disposition for a scotopic hue of violet of about 463 nm. The observation may be explained on the basis of Helmholtz's theory of complementary negative afterimages, provided that (1) the assumption that neutral white is observed when the three types of cone receptors are activated to about the same degree, is rejected, and (2) the origin of the scotopic contrast hues is assumed to be located centrally to the photochemical systems of the receptors.     

The effect of stimulus preexposure upon the context effect in taste-aversion learning in noradrenaline-depleted rats

The present investigation was designed to study the effect of preexposure to a saccharin plus noisy bottle stimulus compound, or to each element by itself, upon the extinction-dependent "context effects" (due to the presencelabsence of the noisy bottle contextual cue) in taste-aversion learning, following noradrenaline (NA) depletion via a single systemic DSP4 injection. Since contextual manipulations have provided a reliable means of studying selective attentional processes the current theorising on the role of noradrenaline can be effectively accommodated. It was found that, under the No Preexposure and Noisy Bottle Preexposure conditions, the "context effect" during the saccharin preference tests, after reinstatement of the noisy bottles for all groups, was totally absent for the NA-depleted rats; in the Saccharin plus Noisy Bottle Preexposure condition the "context effect" was partially blocked for the NA depleted rats and in the Saccharin Preexposure condition it was at least as strong as in the control condition, These findings may be interpreted as supporting our conclusions, concerning NA-depleted rats derived from several different investigations, i.e. that following NA loss rats fail to attend sufficiently to contextual cues in taste-neophobia and taste-aversion situations. Thus, the attentional deficit may be described as an inability to attend to all aspects of the taste stimulus plus exteroceptive context stimulus compound. Although the selective attentional hypothesis of noradrenaline function requires a good deal of alteration, it remains the most parsimonious account that can be described at present.
